Attr Column in Debug Looks strange on resize while value highlighted

Win7IETester v 0.4.2

While I am editing a value in the Attr window of the debug (so it is highlighted) and I decide that I can't see enough of the css attribute (ex. If the attribute that I am editing is "padding-bottom" I can only see "padding-") and I extend that column with with the little handles (value still highlighted), either the edit column stays the same size in the same place or it gets forever lines on the right.if you cannot reproduce, i will make some screenshots.
